Devices for external installation must be placed on a level concrete foundation (chapter 4.2.4). For exact
position and dimensions of pipe connections, see dimensional drawings of the device (chapter 7.1).
Along with pipes for the hydraulic connection, install also pipes with wire rope (it is advisable to separate
the power / sensors). This wire rope is used to pull the device’s power supply cable from the DHW room
and the communication FTP cable for controlling the device. For the appropriate diameter of the power
cable, see technical data (chapter 7.2).
Make a sink for the condensate forming in the evaporator of the device underneath the concrete
foundation. The sink must be under the frost limit to ensure unobstructed drainage. The pipe for
condensate drainage must be installed lower than the hardware connections of the DHW room and
device. It can also be routed to the rain water sink; in this case freezing of the pipe must be prevented.
WARNING
If the condensate drainage is fed to faecal sewage, a suitable syphon must be installed on
the drainage pipe. Otherwise, the presence of ammonia can lead to corrosion of vital parts
of the device and malfunction of the device.
4.2 Location of the device
CAUTION
The concrete pedestal must carry the weight of the device. See technical
information.
The device must be screwed to the concrete pedestal because of the possibility of
strong gusts of wind.
The device must be levelled
NOTE
It is obligatory to consider the minimal clearance from obstacles for ensuring unobstructed
access for maintenance and service of the device.
NOTE
The location of the device has to be accessible with manual transport devices to ensure
undisturbed delivery of replacement parts and equipment for maintenance and servicing.
Costs connected with hiring special equipment for installing the device, servicing and
maintenance are charged the operator separately and are not subject of the warranty.
The device must not be set up at a location which is subject to stronger and lengthy gusts of wind (i.e.
bora wind); they could obstruct the normal air circulation through the evaporator which could result in
disruptions in operation.
In case the device is installed in the wind direction, it is necessary to install adequate wind protection.
Wind protection must be robust enough to prevent the influence of the wind. The best option is
a concrete or brick version.
The height and width of the wind protection must be at least 150% of the basic dimensions of
the device. Only these dimensions enable adequate wind protection of the device.
